BICYCLE-BELL CLAMP.

SPECIFICATION forming part of Letters Patent at; 616,015, dated December13', 1895;;

Application filed October 29, 1898. Serial No. 694,912. (No model.)

1 Clamps, of which the following is a full, clear,

and exact description, whereby any one skilled in the art can make anduse the same.

My invention relates to the class of devices used for securing a bell orthe like to the handle-bar of a bicycle or other part of a vehicle; andthe object of my invention is to provide a device of this class wherebyan easy and quick attachment may be made to a handle-bar or the likewith the parts of the device assembled; and a further object is toprovide a clamp that shall beautomatically adjustable to handle-bars orthe like having a wide range as to sizes and without the use of specialtools. j I

To this end my invention consists in the device as a Whole, in thecombination of parts, and in the details and their combination, ashereinafter described, and more particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a view in elevation of a bellhaving my improved clamp. Fig. 2 is a plan view of the base with thegong removed. Fig. 3 is adetail view, in vertical section, through thebell, with the striking mechanism removed and showing the clamp closed.Fig. 4 is a like view showing the clamp open. Fig. 51s a detail view, onan enlarged scale, of the post and in section through the carrier. Fig.6 is a detail plan view of the carrier.

In the accompanying drawings the letter (t denotes a support, as ahandle-bar of a bicycle b, a base for supporting the bell-strikingmechanism; 0, the bell-striking mechanism; cl, the thumb-lever, and ethe clamp-plate of a bell especially adapted for use with my improvedclamp. A post f is loosely mounted in the base, extending therethrough,and bears on its upper end a gong g and on its lower end a carrier h,that is screw-threaded for the reception of the post. Rigid jaws 2' arepivoted to this carrier and project through the clamp-plate, the jawsbeing curved to fit a handle-bar orilike part. A carrier-socket 7c isformed in the clamp-plate e for the reception of the carrier, the wallsof this socket forming a stop for the jaws. In the form shown the jawsare suspended from pins 7t, located on the carrier 'h in a manner topermit a free swinging movement of the jaws under certain conditions.The post f has a head f, located underneath the carrier, and a shoulderf adapted to rest on the base I).

In the operation of the device, the post f being turned, as by means ofthe gong g, the carrier h is drawn upward, carrying with it the jaws 2'.These jaws are pivoted to and have a swinging movement on the carrierand are extremely rigid and free from flexibility, so that as the jawsare drawn inward the backs thereof, coming in contact with the stop e,force the jaws toward each other and tightly grasp any article placedbetween them. The stop 6' maybe properly termed a gripping-stop, for thereason that it not only prevents separation of the jaws beyond a certaindegree, but-also causes them to move toward each other in thelongitudinal movement of the jaws to tightly grip any article placedbetween them-.

The peculiar construction of the device enables the jaws to be pivotedon the carrier at points quite close'together, thus insuring a compactdevice, and the forming of the jaws, when so pivoted, to grasp anarticle of considerable size causes that part of the jaws coming incontact with the gripping-stop to be arranged at such angle to the plane(crosswise of the jaw) of longitudinal movement of the jaws that a greatswinging movement of the jaws is obtained in a comparativelyslightlongitudinal movement thereof, thus accommodating the device tosupports to which it may be attached having a wide range of sizes.

The device has marked advantages over devices of the prior art in thatit is applicable to a wide range of sizes of supports in a comparativelyslight movement of the carrier. The device is so constructed that theparts are always assembled and there is no danger of loss andconsequentdelay in taking the device apart for the purpose of placing it inposition, as is the case in prior devices. The difficnlty ofreassembling the parts present in prior devices is absent from myimproved structure.

I claim as my invention- 1. In a bracket attachment for bicycles, abasehavinga stop to control the movement of swinging jaws, a carriersupported by the base and having movement in an axial direction thereof,rigid jaws pivoted to the carrier and adapted to be moved inward bycontact with the stop and means for moving the carrier in an axialdirection.

2. In a bracket attachment for bicycles and the like, in combination, abase having a stop, a carrier supported by the base, jaws pivoted to thecarrier and having a swinging movement controlled by contact with thestop, a post secured to the carrier and means for moving the post tocause the movement of the carrier.

3. In a bell, in combination, a base having a stop, a gong,bell-striking mechanism, a carrier located in the base and having amovement in an axial direction thereof, rigid jaws pivoted to thecarrier and protruding from the base and having a swinging movementcontrolled by contact with the stop, and means for moving the carrier inan axial direction.

4. In a bicycle-bell clamp, in combination, a base adapted to supportbell-striking mechanism and havinga stop, a post supported by the base,a gong secured to the post, a carrier supported by said post and havinga movement in an axial direction of the base, rigid 3 g jaws pivoted tothe carrier and having a swing ing movement controlled by contact withthe stop on the base, and means for rotating the post to cause movementof the carrier.

5. In a bicycle-bell, in combination, a base adapted to supportbell-striking mechanism and having a stop, a post supported by the baseand rotatable therein, a gong secured to one end of the post, a carriersupported by the post within the base by interengaging screw-threads,and rigid jaws pivoted to the carrier and protruding from the base.

6. In a bicycle-bell in combination, a base having a stop and adapted tosupport bellstriking mechanism, a post supported by the base, a gongsecured to one end of the post, a carrier secured against removal to theopposite screw-threaded end of the post and within the base, and rigidjaws pivoted to the carrier and protruding from the base.

7. In a bicycle-bell in combination, a base adapted to supportbell-striking mechanism, a post supported by the base, a gong secured tothe post, a clamp-plate having a stop, a carrier secured to the post byinterengaging screw-threads and within the clamp-plate, and rigid jawspivoted to the carrier and protrudin g from' the clamp-plate.
